About this app

HushLog is a private sleep-sound journal that helps you review the important moments from your night. Start a recording before bed, then explore a clear morning summary, a sound-event timeline, and playable highlights.

Candidate sound detection runs on your device. You can label or correct events, save meaningful moments, add notes and factors, compare patterns across nights, play offline sleep sounds, and set a wake alarm. Audio stays in HushLog's private device storage by default and is never uploaded automatically. The app has no ads. Google Analytics for Firebase and Firebase Crashlytics receive limited app-usage and stability diagnostics, but never your recordings, notes, body measurements, or Health Connect data. Advertising-ID collection and ad personalization are disabled.

HushLog is a personal journal, not a medical device. It does not measure sleep stages, detect sleep apnea, or provide diagnosis or treatment advice.
